This invention relates generally to water closets, and more particularly to an improved type of water closet for use in railway cars and constructed with the bowl outlet and the draft outlet in vertical alignment. My invention differs in one important respect from these prior art 2 Claims.

constructions in that the draft outlet is horizontally spaced from the bowl outlet. This horizontal spacing results in a number of advantages. First, the draft chute need not, pass through the floor a foot or more away from the car wall as must be the case with the prior art hoppers. My invention accordingly permits the positioning of the draft chute immediately adjacent the car wall. In some installations, as for example, in the upper roomettes of two-deck Pullman cars this positioning of the draft chute next to the car wall is a very important advantage as the drain pipe from the upper roomette hopper may then be carried through the lower roomette inconspicuously and with greater economy of space. Further, my invention for the first time provides a water closet characterized by a vertical closure for the draft outlet, instead of the horizontal closures previously employed. This vertical closure requires less angular displacement to obstruct the draft opening and thus is speedier and more positive in action. Still further, my vertical closure construction allows the use of smaller and cheaper draft chutes; for'example, I can employ a chute 4 inches in diameter with my invention in comparison to the 7 inch chute required with the conventional hopper.

It is the principal object of this invention, therefore, to provide for railway cars and the like a water closet wherein the draft outlet is hori zontally spaced from the bowl outlet, thus adapt ing said water closets to meet changing conditions of design in said railway cars and the like.

The foregoing and such other advantages, objects, and capabilities as may appear herein or be pointed out as this description proceeds, or as are inherent in the present invention, are illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of a water closet embodying my invention, showing the foot pedal in its normal raised position;

Figure 2 is a plan view of the water closet shown in Figure 1; and

Figure 3 is a side elevationsimilar to Figure 1 but showing the foot pedal in depressed position as when the flushing operation is half-way completed, and omitting a number of lesser interior parts in order to expose more clearly the working of other more important parts.

Like reference characters indicate similar parts in the drawings and in the description of invention which follows:

Referring now more particularly to the drawings the numeral 4 indicates generally a water closet hopper preferably made of vitreous china; but which, of course, maybe constructed of metal or any other suitable material. The hopper 4 comprises a hollow stand portion 5 and a bowl integral therewith and supported thereby. As best shown in Figure 3, the bowl 6 is constructed with a depending portion 7 open at the lower end thereof to form the bowl outlets. This bowl outlet 8 is normally closed by a dump pan 9 which is rigidly secured to a rotatable shaft l0 extending transversely through the hopper 4 in front of the depending portion 1.

In the mid-portion of'the hollow stand 5 is formed an interior, annular flange H. A pipe 12 extends into the stand 5 through an opening in a rear wall thereof below the flange l I, and said pipe terminates in an upwardly projecting portion I3. The pipe i2 is supported by a bracket 14 (Figure l) fixed to the stand 5 by a bolt I la and engaged by a pair of screws 15 and It depending from a boss I! formed in said pipe. Ro-

tation of the screws 15 and it in the proper direction will raise the boss ll and the pipe I2 until the upwardly projecting portion I3 is firmly seated against the flange l l as shown in the drawings. The pipe l2 communicates from the interior of the stand 5 to the vertical draft chute [8 rearwardly positioned from said stand. The end IQ of the pipe I2 projects into the chute. A draft plate 20 is rigidly secured to the shaft Zl extending transversely through the chute [8. Normally, the plate 20 is in open position with respect to the pipe end Zll as shown in Figure 1, but upon rotation of the shaft 2| in the sequence of the flushing operations hereinafter described, the plate 29 is brought against the pipe end I9 to close the draft outlet 22.-

From a starting position of parts as shown in Figure 1, means are provided for successively opening a flushing valve 29 to supply Water to the bowl 6, closing the draft outlet 22, opening the bowl outlet 8, shutting off said flushing valve 29, closing said bowl outlet 8, and opening said draft outlet 22. The flushing operation is commenced by depressing the foot pedal 23 pivoted upon the floor bracket 24. Depression of the foot pedal 23 translates 'upwardlyithe adjustable link '25. The link 25 and its functioning are fully described in Patent No. 2,278,887, issued April 7, 1942, to the Duner Co. of Chicago, Illinois, as assignee of Nels Larson. The upward translation of the .l-i-nkZE rotates counterclockwise the crank arm 26 and the shaft 21 to which said orankarmiisrflxed. l

Also fixed to the shaft 2'! is a u shaped-arm fl, the rotation of which with theshaft.21,.operates a flushing valve 29, exemplified herein as similar to the valve described in Patent No. 1,711,635,.

issued May 7, 1929, to John C. Duner.

The compression of the spring 4! builds up a force to return the dump pan 9 to its :originalclosed position in the reverse half of the flushing operation. This reverse half of the flushll'lg operation is initiated by releasing pressure uponth'e foot pedal. The weight of the adjust- .ablellink 25 causes it to drop and to rotate the crank arm 26 clockwise, in turn rotating the U:-shaped arm 28 and closing the valve 29. The

The dropping of a counterweight 46 fixed to the draft plate shaft 2! swings the draft plate-2|] to its original open position. The operating mechanism is thus fully returned to its starting position.

From the foregoing it is apparent that I have invented a novel watercloset particularly advantageous to use in railway'cars and other moving vehicles. Economy of space is the principal consideration involved in the design. of such-cars and vehicles, and my novel Water closets incorporating horizontally spaoedbowl and draft outlets permit 'the'niost efiicient allocation of space My invention having been thus described and its utility indicated, the scope of said invention is defined in the appended claims. But in connectiontherewith, it is" to be understood "that the foregoing description has been specific: for the purposes of illustration" only and that 'I'i-nten'd'to embrace as my invention all the modifications thereof Within the scope of said appended claims.
